GEELMUYDEN. ASTRONOMICAL OBSERVATIONS. [NORW. POL. EXP. 



The observations themselves seem to require a somewhat greater correction to the watch, 

 but as the altitudes were taken on both sides of the meridian, the result would be essentially 

 the same. This result has been adopted for the latitude of the Winter Hut. 



1896, April 29. Bar. 752 mm, Temp. - 11.5 C. Ass. Hor. Point 89 52' -f x. 



The mean result is x = + 0'.6 and 



Watch I 6h 30m, LT-I = - 54m 538. 



1896, May 16. Bar. 758.5 mm, Temp. - 6 C. 



Circle Hor. Point = 89 51' + x, Sun's Semidiameter = Tabular Value + y. 



The values x + y = + 149" and x y = 94" were determined with omission of the 

 first observation. If it is also omitted for the clock correction, the result is 



Watch I 8h 36m, LT-I = - 57" 24. 



Immediately after these observations, the bearing of the Sun and of a terrestrial mark 

 were taken with the theodolite, and then a series of bearings by compass of the same terrestrial 

 mark and some other points, which were useful for the reduction of the observations taken on
